Abstract

A photochromatic compound represented by the following general formula (I): <CHEM> where: R1 and R2 independently represent a linear, branched or cyclic C1-C10 alkyl radical, H, OH, F, Cl, Br, NH2, N(R4)2, COOH, OR4 or COOR4 where R4 is a C1-C10 linear, branched or cyclic alkyl radical, or an aryl radical; R3 is a variously substituted mono or polycondensed heterocyclic or aryl radical. A compound (I) demonstrates marked photochromatic characteristics both when in an organic solvent solution and when incorporated into polymer matrices.
